The South Pole Telescope (SPT) is a 10-m mm/sub-mm telescope at the Amundsen-Scott South Pole Station. It's primary science goals consist of a galaxy cluster survey for understanding Dark Energy and probing the physics of Inflation through the CMB polarization. Both science goals require exceptional sensitivity requiring focal planes with many optical elements. The focal planes of the SPT...

We are building large arrays of feedhorn-coupled superconducting transition-edge sensor (TES) polarimeters to measure the polarization of the cosmic microwave background (CMB) radiation. These polarimeters will be deployed on three experiments in the coming year: the Atacama B-mode Search, the South Pole Telescope Polarimeter, and the Atacama Cosmology Telescope Polarimeter. The science...

We present recent developments of Aluminum (Al) Superconducting Tunnel Junction (STJ) and Microwave Kinetic Inductance Detectors (MKIDs) for future measurements of the cosmic microwave background (CMB) polarization.
In an attempt to understand the mechanism of inflation in the early universe, we focus on observing the B-mode polarization pattern of the CMB. The pattern is known to carry...

The standard detector in X-ray Astronomy is CCD (charge coupled device) at the moment because of the remarkable imaging capability (~20 um pixel) and energy resolution at the fano limit (FWHM~135 eV@ 6keV). However, the time resolution of CCD is poor (~1 Hz); this limits the observation of bright X-ray sources such as black holes. Thus, we have been developing a novel monolithic active pixel...

High energy gamma-ray astronomy has become a very promising field. On the other hand, in MeV region, there still remain many unobserved interesting celestial objects such as black holes and Gamma-ray Bursts. To explore this energy range, we have developed Electron Tracking Compton Camera (ETCC) consisting of a gaseous Time projection Chamber (TPC) based on the micro pixel gas counter (-PIC)...

Super-Kamiokande (SK), a 50-kiloton water Cherenkov detector, is one of the most sensitive neutrino detectors. SK can be used also for supernova observations by detecting neutrinos generated at supernova. In order to improve the performance of the detector for supernovae, we are developing two new features, one for recording all information within one minute and the other for recording...

Laser cavities and interferometers are approaching MW beam power, enabling probes of new microphysics and of space-time itself at mass scales well beyond the TeV scale. I will discuss several applications currently being developed, including 1) a next-generation photon-axion oscillation experiment; 2) the Holometer--an experiment to detect Planck-suppressed space-time uncertainty; and 3)...

The current interferometric gravitational wave detectors are being upgraded to what are termed ‘2nd generation' devices. Sensitivities will be increased by an order of magnitude and these new instruments are expected to uncover the field of gravitational astronomy. A main challenge in this endeavor is the mitigation of noise induced by seismic motion. Detailed studies with Virgo show that...

Microwave emission from ultra-high energy cosmic ray (UHECR) air showers presents the possibility of developing a novel detection technique. This new technique possesses the advantage of the fluorescence detection technique - the reconstruction of the longitudinal shower profile - combined with a 100% duty cycle, minimal atmospheric attenuation and the use of low cost commercial equipment. ...

Detection of ultra high energy cosmic rays, generating an air shower in the atmosphere of the Earth, is usually performed through the detection of secondary particles at the surface or through the detection of the fluorescence light generated in the sky. The latter has the advantage of providing a longitudinal profile of the shower development, and the disadvantage of a limited uptime of only...

The First G-APD Cherenkov Telescope (FACT) project aims to prove that newly developed Geiger-mode avalanche photo-diodes (G-APD) are a viable alternative to widely used vacuum photomultipliers tubes (PMT) for future Cherenkov telescopes for ground-based gamma-ray astronomy.
Compared to PMTs, G-APDs (also called SiPM or MPPC) are much more compact, need a low bias voltage, are less fragile to...

The use of suborbital rocket payloads to perform intriguing science in only 5 minutes continuously requires the use of new and innovative technologies. High resolution X-ray spectroscopy necessitates large collecting areas and large fields of view to achieve adequate countrates in this short amount of time. One method of increasing the signal is to use large format detectors. Stitching...
